So firstly, add px onto both sides of the equation: $r=-8x+px-2$

Next, add 2 to both sides of the equation: $r+2=-8x+px$

Next, factor out -x on the right side of the equation: $r+2=-x(8-p)$

Next, divide both sides by (8 - p): $\frac{r+2}{8-p}=-x$

Lastly, multiply both sides by -1 and <u>your answer will be $-\frac{r+2}{8-p}=x$ </u>

The Centers for Disease Control and Prevention Office on Smoking and health is the lead federal agency responsible for comrehens

storchak [24]

Answer:

a) The percentage of adults who smoke are decreasing with time. b) the equation that best described this data is y=-0.3364x+22.809 (R^2=0.859) in which y is the percentage of adults who smoke and x the number of years. c) the percentage of adults who smoke will be 19.8% and it will not meet the expected 12%, it would take 32 years to reach that value.

Step-by-step explanation:

The data can be plotted to which years is the independent variable and percentage of adults who smoke is the dependent variable. The linear trendline that described this data has a negative slope which indicates that the percentage of adults is decreasing with time. In order to determine if the OSH target is being met, the x is replaced by 9 which is the goal period of nine years. The y is 19% which is higher than the 12% goal. In order to know the period it will take to the reach the goal of 12%, the y is replaced by 12 in the curve and the x is the answer in years = 32 years.

taki has her back to a wall. she starts to walk straight forward. she stops and turns 133° to the right and walks back in this d

Nikitich [7]

I'd like to assume that the triangle is a right triangle and you solve for x so...

133 + c = 180 (supplementary property to find one angle of triangle)
c = 47

x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43

Therefore, x is 43 degrees

For a 95% confidence interval, the corresponding z-score is 1.96. Therefore the deviation will by 1.96*0.5 lbs = 0.98 lbs. Therefore, the confidence interval will be (5 - 0.98, 5 + 0.98), which is (4.02, 5.98). The weight range is from 4.02 lbs to 5.98 lbs.

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.
